This scoping study aims to investigate the circularity design tools implemented in the electrical and electronics industry, identify related business cases, and analyze noteworthy design characteristics. Numerous circularity-related keywords are extracted from 17 tools by following the selection criteria. A total of 11 main characteristics and 47 sub-characteristics are identified based on four implementation scenes, including business model innovation, product design, service design, and supply chain management. Service-led approach in business model innovation, societal and emotional aspects in product design, service design during use, and collaborative distribution and logistics in supply chain management are key characteristics that must be considered to achieve a high level of circularity. Applying advanced digital technologies in servitization can enhance product performance and overcome circularity challenges in the industry. Moreover, a method for measuring the circularity performance of a product from the societal and emotional perspectives and its associated services is yet to be developed. Future studies should further investigate how qualitative circularity indicators can pragmatically be applied, improve stakeholder and community engagement, and increase academic–industry collaboration when innovating a circularity design and assessment tool.
